A clinic took temperature readings of 250 flu patients over a weekend and discovered the temperature distribution to be Gaussian, with a mean of 101.40 °F and a standard deviation of 0.5900 °F. Use this normal error curve area table to calculate each value. What is the fraction of patients expected to have a fever greater than 102.70 °F? fraction above 102.70 °F: What is the fraction of patients expected to have a temperature between 101.28 °F and 101.93 °F?
